Scrubber burner

A scrubber burner comprising:

• a mixed burner module comprising:
• a mixed spray ring on which multiple spray holes penetrate from an outer circumference of the mixed spray ring to an inner circumference of the mixed spray ring and that sprays mixed fuel gas in a mixed combustion space formed within the inner circumference of the mixed spray ring;
• a mixed guide ring positioned radially outward from the mixed spray ring and separated from the outer circumference of the mixed spray ring, the mixed guide ring equipped with multiple guide holes that penetrate from an outer circumference of the mixed guide ring to an inner circumference of the guide ring;
• and
• a mixed housing that is separated from the outer circumference of the mixed guide ring to form a mixed gas channel between the mixed housing and the mixed guide ring through which the mixed fuel gas flows;
• a preheat burner module located directly above or directly below the mixed burner module, the preheat burner module comprising:
• a preheating spray ring that is formed with a porous material comprising one of metal fibers, metal foams, packed beads, ceramic foams, nano-sized porous media and porous sintered metals and that preheats a fuel gas before providing the fuel gas to a preheating combustion space formed inside the preheating spray ring;
• a preheating guide ring around the outer circumference of the preheating spray ring and equipped with multiple preheating guide holes that penetrate from an outer circumference of the preheating guide ring to an inner circumference of the guide ring;
• and
• a preheating housing that forms a ring shaped gas channel that is separated from the outer circumference of the preheating guide ring and through which the fuel gas flows
• wherein the mixed combustion space is connected to the preheating combustion space;
• and
• a lower spray module that is located directly below the preheating burner module or directly below the mixed burner module, the lower spray module comprising:
• a lower spray ring comprising a lower spray hole that sprays lower fuel gas into a lower combustion space that is connected with the preheating combustion space or the mixed combustion space;
• a lower housing that wraps the outer circumference of the lower spray ring to form a lower gas channel in the shape of a ring through which the lower fuel gas flows and that is equipped with a lower outer wall hole that penetrates from the outer circumference to the lower gas channel, and wherein the lower spray hole sprays lower fuel gas from the lower gas channel.
